高能重离子碰撞中的色玻璃凝聚态产生

Production of Color Glass Condensate in the Heavy-ion Collisions

在高能重离子碰撞中,当碰撞能量很高或者Bjorken变量的值很小时,强子波函数中单位转移区域的胶子密度将会变得很大而导致胶子分布出现饱和,即色玻璃凝聚态(colour glass condensate,CGC)。据此,简要综述了高能重离子碰撞中色玻璃凝聚态(colour glass condensate,CGC)的产生及其性质。

In the heavy energy heavy-ion collisions,the density of partons for per unit trans-verse area in hadronic wavefunctions becomes very large leading to a saturation of parton distributions at very high energy or small values of Bjorken x.In the paper,we review the properties of the colour glass condensate that produced in the heavy energy heavy-ion collisions.
